This open redirect vulnerability resides within the login flow and allows an attacker to craft a malicious URL that, when accessed by an authenticated user, redirects them to a spoofed login page. The attacker hosts this spoofed page to mimic the legitimate Aruba login, prompting the user to enter their credentials. This attack is particularly dangerous because the user, after submitting their credentials on the fake page, may be redirected to the real login page, making the attack less obvious. This vulnerability impacts the security of the HPE Aruba Networking Private 5G Core On-Prem systems by potentially allowing unauthorized access through stolen credentials.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker crafts a malicious URL containing a redirect to an attacker-controlled server.

This allows an attacker to gain unauthorized access to the system's administrative functions and sensitive data. The impact could range from data breaches and service disruption to complete system takeover, depending on the privileges of the compromised account.
